To all whom z'tmoy/ concern.:

Be 1t known that I, WILLIAM: H. Tuinman,

a citizen of the United States, residing at are detachably mounted upon a supporting base or flange carried by each shaft section. It is the object of the invention to provide simple, effective, and economical means for securing the bearing blocks totheir supporting bases. I accomplish the foregoing objects in and through. the construction illustrated in the drawings forming a part hereof, wherein Figure l represents an elevation of two shaft sections united by a universal joint embodying my invention, cer tain parts being shown in section; and Fig. 2 a sectional view corresponding to the line 2-2 of Fig. 1.

Describing the various parts by reference characters, 1 and 2 denote the shaft sections which are united by the universal joint and 3 and t the hub members secured to said shaft sections, respectively. Each of these hub members is provided with a supporting base 5, and each supporting base is provided with a pair of seats 6 for bearing blocks. Each seat is shown as provided with a trans verse rib 7 having a wall or face 8 which is adapted to engage the coperating face 9 of a bearing block 10.

Each of the bearing blocks shown herein is provided with a bore 11 extending from the inner face thereof toward but not providing a well 12 for lubricant. Mounted Within each bore is a bushing 13 which receives therewithin the trunnion 14. of a cross member 15 having a central lubricant well 16 from which lubricant may be conducted through radial ports 17 in said trunnions to each of the wells 12, thereby to lubricate the bearing formed between the inner wall of the bushing 13 and the outer wall of the coperating trunnion.

Each bearing block is provided with a stud 18 mounted within a bore 19 provided therefor in the appropriateside of itssupporting base.

`For the purpose'of anchoringl the bear-- mg blocks `upon their seats, the following construction is providedrEach studlSis provided with a slot 20 extending transversely of the outer face thereof and having a flat seat 21. Intersecting the bore 19 is a bore 22 extending across each side of the base 5, the upper wall 22a of said bore which faces the seat 6 4being inclined. l

.Mounted within the bore 22 is a locking pin 23 having a straight flat face 24 cooperating with the slot 2O in the stud 18 and havlng also a flat face 25 adapted to engage the flat seat 21 of said slot. The bore 22 is shown as extending beyond the flat seat 21 of the slot 211. The smaller end of the p in 23 is reduced and threaded and provided with a nut 26, a split washer 27 being provided for the purpose of preventing the unscrewing of the nut.

With the parts constructed and arranged as described, each bearing block will be inserted within its appropriate bore with the slot 20 facing the tapered bore 22.` The pin 23 willbe inserted within the bore with the face 24 in the slot and the face 25 of the pin in position to engage the flat wall or seat 21 of said slot. By setting up on the nut 26, the pin 23 will be drawn along its bore and, because of the inclination of the bore, the pin, pressing upon the upper tapered surface of said bore, will in turn thrust upon the wall or seat 21 of the recess or slot'which is remote from the seat 6, thereby forcing the bearing block to its seat.

Having thus described my invention, what I claim is: 4

1. In a universal joint, the combination of a supporting base having a seat and a bore extending from said seat `and a bore extending transversely of and intersecting i the first mentioned bore at one side thereof,

Wall of the slot, whereby, through the adjustment of the pin along its bore, the stud vWill be movedalong the first mentioned bore v Yto'cdravvthe bearing block to its seat.

2. In a universal joint, the combination of a supporting base having a seat and e bore extending roni sind seat and t bore extending transversely of and intersecting Y having a stud projecting into the first bore,

said stud being' provided in one side thereof with a slot having a Het Wall registering With the second bore and located above the portion of said bore which is remote iron'i said seat, said Wall being` nearer to said seat than the inclined Wall of the second bore, and a looking pin having :in inclined rounded Wall adapted to cooperate with the inclined Wall of the second bore and having :L Het Wall opposed to such inclined wall und adapted to engage the Ilot Wall of said slot, and means for moving said pin along the second bore and the slot thereby to drew the bearing block to its seat.

In testimony whereof, I hereunto nllix my signature.

WILLIAM H. THIEMIQR.
